No warranties, no guarantees. If this ruins your device, your fault, not mine. Consider this a test build, backup important stuff manually to your PC for now (photos etc)

This requires an sdcard installed

Can confirm root as I'm currently running it on my tablet. Bliss did it himself and is going to package it and release it in a couple of hours.

Thanks to everyone for their hard work with this.

Thanks for sharing this it worked great, except for the instructions I needed to use
dd if=/data/local/cwr_ventana_2.img of=/dev/block/mmcblk0p1
rather than
dd if=/data/local/cwr_recovery.img of=/dev/block/mmcblk0p1
to match the name of your file.
Thanks again for sharing, CWR seems to be running perfectly.
Also for those looking for root the exploit has been posted here.

I installed it. It works. Though /sdcard cannot be found and backup doesn't work. But I'm sure these will be figured out in the near future :)

I've got it installed just fine and even got the back up files

Gonna do a clean install and then see about dumping the images

ClockworkMod Recovery boots for me and was backing up but failed while it was backing up /data for me (I have tried twice now). It seems to backup /system just fine though, I don't know why it would fail during the /data backup. Has anyone else successfully made a backup yet?

failed to restart in recovery for me (exactly as redBaron)
Try to install CWM 3 times

OK, booting in recovery works fine, but NOT via Rom Manager !
(only by pressing and releasing vol+ button when booting)

Yes ... one has to take great care with naming files ... I did something similar and used Root Explorer to rename the cwr file correctly.

I am very excited to see this news - though i'm going to wait until there is a semi-stable, well establish path for Root. Hopefully this achievement leads to the Thinkpad Tablet getting much more attention, its a pretty badass tablet and should prove to be a pretty good performer once all the Lenovo crapware is tossed out. Glad I remained faithful and patient!

    Here are new versions for the different Sizes:

    16Gb:
    http://everyrandom.com/files/download.php?file=264ventana_recovery.img

    32Gb:
    http://everyrandom.com/files/download.php?file=196ventana32_recovery.img

    64Gb:
    http://everyrandom.com/files/download.php?file=538ventana64_recovery.img

    Credits go to Logxen for modifying and compiling (based on the builds jcase made).
    Thanks to bohdans for webspace.

    We also excluded the /data/media directory (Internal sdcard) so backups doesn't need so much space anymore.

    P.S. there may still be bugs, i you find one, post as much information you can provide and your tpt model

    P.P.S: As always: No warranties, no guarantees. Playing around with the recovery can brick your device.


    Known Bugs:
    - Doesn't work on ROW Roms
    - Force reboots while backup on some devices

    the CWM images are down does anyone have them and could please reuplaod them?

    Here u go bud...and everybody else of course^^
    16Gb Version....
    lil backstory if u care to read...

    i just got a barely used TPT and was in need as well...it has never been updated!!!!
    A Friend of mine got his TPT back then when it came out, i rooted it of course asap^^
    lucky me...coz he did not had a memory card for puttin CWM and stuff on...so i borrowed him one of mine...for some years of course :p
    som time in 2016 i demanded back MY friggin property!!!!....just kiddin^^...hehehe...

    lookin at my new&shiny 4gb SDCard I do remember thinkin: "make an image b4 wipin"....turns out it was not so bad idea afterall...
    u´ll just never no if someone still does care for thiz pice of crap u just tossed out da window coz it frggin sucked:D

    hav phun^^

    I can compile ROW versions with my kernel. Can you tell me what steps you took to exclude /data/media(I'm quite new at this)?

    Also, are your config files uploaded somewhere for the 32 and 64 gig models(I can generate only for 16GB at the moment)?

    You have to edit the source files to force this behavior. Its in the file nandroid.c near line 111:

    if (strcmp(backup_path, "/data") == 0 && volume_for_path("/sdcard") == NULL)

    Erase the second part of the if-condition. Something like this:

    if (strcmp(backup_path, "/data") == 0)
